Real-time monitoring of residual current and temperature, three-phase current, three-phase voltage, frequency, power and four-quadrant electric energy and other electrical parameters monitoring (specific functions see instrument selection);

With residual current protection, temperature protection function;

Provide four switch input function, each way can achieve linkage control;

Provide one relay output function, each can achieve programming control;

With event storage function, the detector can record the alarm occurrence time, type, parameters, according to the alarm record can analyze the scene situation, to provide a basis for eliminating the fault;

Using fieldbus communication technology, the upper computer management software can always monitor the operation of the site and find the alarm information in time. Through the RS485 interface, the standard Modbus protocol can be connected to various standard systems.

High degree of integration, networking, high degree of intelligence, reasonable action characteristics;

Suitable for 04kV voltage class TN-C-S, TN-S and local TT system.
